We have had a Nordictrack treadmill for just under 2 years which we keep in our garage (only place we had room). Nordictrack or ICON do not recommend you keep it in the garage and suggest that it be kept at a temperature of between 15C-20C degrees (although these temperatures are not specified in their manual) and were not happy to replace the belt which became stick on the weekend and tore a little at the edge as a consequence, even though we have had it such a short time and have maintained it to the best of our ability. I am now looking for some sort of fleece cover to keep it warm through the winter, a winter coat if you like. I am very disappointed with Nordictrack, our previous Treadmill from them, we had for 7 years and it was fine in the same conditions and lots of websites suggest even keeping Treadmills outside as long as they are covered properly and kept away from extreme cold and other extreme weather conditions.
